Thanks Naghorse - they do look like a great idea, I have seen some similar ones advertised here in New Zealand but his old owner seems to think he wouldnt tolerate one. I would still like to try one next summer though as I dont like covering his face in sunscreen every day. I am unsure how to clean it off as it builds up - I dont want to be scrubbing his face, gentle washing doesnt seem to remove it. I cant help wondering if its bad for the skin to be constantly slathered in sunscreen even though I use Filterbac. He also has blue eyes and one of them is surrounded in white, this eye seems to be quite sun sensitive and is quite often weepy.
